ELECTRIC LAMP.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed March 11, 1918. Serial No. 221,769.

To all whom it may concern:

Be it known that I, \VALTER J. AVERY, a citizen of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Electric Lamps and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a novel type of electric lamp which will be simple, inexpensive, compact and eflicient, as well as ornamental; and with this general object in view, the invention resides in the novel features of construction herein described and claimed and shown in the accompanying drawing wherein:

Figure 1 is a side elevation; and

Fig. 2 is a longitudinal section. Briefly speaking, the improved lamp comprises vertically elongated body or shank whose upper end portion is permeable to light, said body being of substantially uniform size throughout its height and having an electric bulb in said end, the current be ing supplied to the bulb by feed Wires passing through the body.

More specifically described, the device in cludes a verticallydisposed cylindrical body 1 preferably formed of'wood and of uniform diameter throughout its height with the exception that it is provided near its lower end with an external rib 2 and groove 3, these features being merely for the purpose of giving the lower end of the body substantially the same appearance as a projectile. Formed centrally in the upper end of the body 1 is a recess 4: having its wall threaded at its upper end as shown at 5, while leading from the center of said recess through V the lower end of the body, is a central bore 6.

A preferably metal tube 7 is snugly received in the bore 6 and the upper end of said tube is provided with an electric lamp socket 8 threaded thereon and located in the recess 4. The lower end of'tube 7 may extend through any appropriate base (not shown) with which the device may be equipped, and this tube serves, to receive the wires 9 which supply current to the socket 8; A well known form of electric bulb 10 is received at its lower end in the socket 8 and is, located in a dome-like globe 11. This globe is preferably formed of frosted glass and rests on the upper end of the body 1, being of the same diameter as said body and having a depending flange 12 threaded into the upper end of the recess 4. The relative dimensions of the bulb 10 and flange 12 are such as to permit the former to pass through the latter when it is necessary to install a new bulb.

From the drawing, it will be seen that the globe 11 is shaped to correspond substantially to the contour of a projectile nose and thus the general appearance of the device is that of a projectile with an illuminated end. In addition to its novel ornamental qualities, it is obvious that the invention will be efficient, may be easily and inexpensively manufactured, and is extremely compact. Since leading from said recess through its lower end, a tube received snugly in said bore, a

lamp socket on the upper end of said tube located in said recess and spaced from the Wall of the latter, feed wires for said socket passing through said tube, an electric bulb whose lower end is received in said socket, a dome-like globe permeable to light and receiving said bulb therein, said globe resting on the upper end of said body and having a depending flange surrounding said socket and threaded into the upper end of said recess, the lower end of said globe and the upper end of said body being of substantlally the same size.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
